Medical devices with broad spectrum antimicrobial activity
Inventors:Raad; Issam (Houston, TX), Hanna; Hend A. (Houston, TX), Nabulsi; Nabeel (Katy, TX)
Assignee:
Board of Regents, the University of Texas System (Austin, TX)
Filed: 19 Oct 2007
Abstract:
The present invention provides novel broad spectrum antiseptic compounds that further have properties that allow them to be coated/impregnated into polymer surfaces. Methods for coating these antiseptic compounds onto medical devices especially indwelling medical devices to prevent the growth of pathogens in such devices and hence, to prevent infection to patients via such devices are provided. The invention also provides antiseptics that are useful as general surface disinfectants and sterilizers, fluid disinfectants and biocide preservatives.

Process and compositions for the disinfection of waters
Inventors:Barak; Ayala (Jerusalem, IL)
Assignee:
Bromine Compounds Limited (Beer-Sheva, IL)
Filed: 02 Oct 2008
Abstract:
A process for killing microorganisms and controlling biofouling in high chlorine demand waters comprises mixing two components, one of which is an oxidant and the other an ammonium salt, and adding the mixture immediately to the aqueous system to be treated.

Surface topographies for non-toxic bioadhesion control
Inventors:Brennan; Anthony B (Gainesville, FL), Baney; Ronald H. (Gainesville, FL), Carman; Michelle L. (Ocala, FL), Estes; Thomas G. (Marietta, GA), Feinberg; Adam W. (Cambridge, MA), Wilson; Leslie H. (Gainesville, FL), Schumacher; James F. (Gainesville, FL)
Assignee:
University of Florida Research Foundation, Inc. (Gainesville, FL)
Filed: 05 Dec 2006
Abstract:
An article has a surface topography for resisting bioadhesion of organisms and includes a base article having a surface. A composition of the surface includes a polymer. The surface has a topography comprising a pattern defined by a plurality of spaced apart features attached to or projected into the base article. The plurality of features each have at least one microscale dimension and at least one neighboring feature having a substantially different geometry. An average feature spacing between adjacent ones of the features is between 10 .mu.m and 100 .mu.m in at least a portion of the surface. The surface topography can be numerically represented using at least one sinusoidal function. In one embodiment, the surface can comprise a coating layer disposed on the base article.

Method for sanitation of dental water lines
Inventors:Fillery; Edward David (Toronto, ON, CA)
Assignee:
Not listed
Filed: 14 May 2008
Abstract:
An automated flushing system removes stagnant water and the micro-organisms it contains from dental unit waterlines when a dental chair is not in use. The system prevents the exponential replication of micro-organisms in dental waterlines and can be used to increase the contact time of disinfectants with adherent biofilms in waterlines.

Compounds and methods for modulating communication and virulence in quorum sensing bacteria
Inventors:Blackwell; Helen E. (Middleton, WI), Geske; Grant D. (Madison, WI), Wezeman; Rachel W. (Madison, WI)
Assignee:
Wisconsin Alumni Research Foundation (Madison, WI)
Filed: 02 Feb 2006
Abstract:
The present invention provides compositions and methods for modulating the communication and virulence of quorum sensing bacteria. In various exemplary embodiments, the invention provides a combinatorial library of quorum sensing compounds including synthetic analogs of naturally occurring and non-naturally occurring acyl-homoserine lactone (AHL) analogs, and methods of synthesizing and using these compounds.

Proteases, nucleic acids encoding them and methods for making and using them
Inventors:Cayouette; Michelle (San Diego, CA), Hansen; Connie Jo (San Diego, CA), McClure; Amy (San Diego, CA), Sun; May (San Diego, CA), Gramatikova; Svetlana (San Diego, CA), Dycaico; Mark (San Diego, CA), Barton; Nelson R. (San Diego, CA), Stege; Justin T. (San Diego, CA), Aboushadi; Nahla M. (Oceanside, CA)
Assignee:
Not listed
Filed: 10 Oct 2003
Abstract:
The invention is directed to polypeptides having protease activity, polynucleotides encoding the polypeptides, and methods for making and using these polynucleotides and polypeptides. The polypeptides of the invention can be used in a variety of diagnostic, therapeutic, and industrial contexts. The polypeptides of the invention can be used as, e.g., an additive for a detergent, for processing foods and for chemical synthesis utilizing a reverse reaction. Additionally, the polypeptides of the invention can be used in food processing, brewing, bath additives, alcohol production, peptide synthesis, enantioselectivity, hide preparation in the leather industry, waste management and animal degradation, silver recovery in the photographic industry, medical treatment, silk degumming, biofilm degradation, biomass conversion to ethanol diodefense, antimicrobial agents and disinfectants, personal care and cosmetics, biotech reagents, in increasing starch yield from corn wet milling and pharmaceuticals such as digestive aids and anti-inflammatory (anti-phlogistic) agents.

System for calibrating dissolved oxygen analyzers using compressed fluids during cleaning
Inventors:Feng; Chang-Dong (Long Beach, CA)
Assignee:
Rosemount Analytical Inc. (Irvine, CA)
Filed: 18 Sep 2006
Abstract:
A dissolved oxygen measurement system, and a method for calibrating a dissolved oxygen analyzer are provided. The method includes directing a pressurized cleaning fluid, having a known oxygen content, upon a sensing surface of a dissolved oxygen sensor disposed in a fluid. Then, the analyzer waits until the dissolved oxygen sensor response to the pressurized cleaning fluid is relatively stable, and stores a calibration value relative to the dissolved oxygen sensor response to the pressurized cleaning fluid. A dissolved oxygen measurement system is also provided. The system includes a dissolved oxygen sensor disposed in a fluid and a first source of a first compressed cleaning fluid that has a first dissolved oxygen content. A dissolved oxygen analyzer is coupled to the dissolved oxygen sensor and to the first valve and is configured to obtain a first calibration value related to the first dissolved oxygen content.
